BINDING-POST.

Specification of Letters Patent. Patented Sept. 13 1910.

Application filed. June 22, 1910. Serial No. 568,262.

To all whom it may concern:

lie it known that I, Tnouns E. MURRAY, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented a certain new and useful Improvement in Bindin Posts, ofwhich the following is a speci cation.

The invention relates to binding posts or wire connectors for circuitconductors, and consists in the construction, more particularly setforth in the claims, \vherebv the device is adapted to hold wires ofdifferentgage and rendered simple and inexpensive.

In theaccompanying dra\vingsl igures l and 2 are side elevations of mybinding post. F ig. 3 is an elevation with the heat and wire in crosssection. Fig. 4 is a vertical cross section. Fig. 5 is a top view, andFig.6 is an elevation, of the head and shank separately: and Fig. 7 isan end view of the sleeve.

Similar letters of reference indicate like parts.

.The shank A and head B are referably formed integrally of sheet metal:suitably shapedand bent, so that the shank is bifurcated. The head iselongated and semi cylindrical. The width of the groove in the head isto be sutlicieut to receive the largest size wire which the device isintended to hold, and may be made V-shaped atthe bottom, as shown at C.The sleeve D may also be made integrally of sheet metal, bent incylindrical form, and fits on the shank. On one edge, or, preferably as-here shown, on both edges of the shank are may be formed similar pairsof recesses H,

I, J, the recesses H being smaller than the recesses G, and the recessesI being smaller than recesses H, and the recesses J smaller thanrecesses I. In this way, I provide, as here shown, six pairs ofrecesses, progressively smaller in size. In the upper edge of the head'B and in roximity to and on each side of the shank A are formed pairsof notches K, L.

In using the device, the wire M is seated in the groove in the head B.The sleeve D is then placed on the shank and adjusted with either enddownward, so that a recess, as J, of proper size correspondin Y to thatof wire M comes over said wire. T iosleeve is then moved down so assecurely to clamp the wire 1n place in said recess and between thesleeveand the head. l/Vhere the wire is, as shown in the drawings, ofrelatively small diameter, the notches K, L in the head permit thisdownward adjustment of the sleeve. A headed screw N is then insertedthrough an opening in any suitable sup ort, as 0, into the shank, andset up, thus olding the sleeve in adjusted positlon upon the wire, andalso securing the whole device to the support.

I claim:

1. A binding post comprising a bifurcated shank, a sleeve thereon havinga plurality of pairs of oppositely disposed recesses in its edge, eachpalr of recesses differing in size from the recesses of the other airs,and the wire to be held being receive in a pair of recesses ofcorresponding size and between said sleeve and the bottom of the shank,and means for holding said sleeve in adjusted position upon said wire.

2. A binding post comprising a bifurcated shank, a sleeve thereon havingin each edge a plurality of pairs of oppositely disposed recesses, eachpair of recesses differing in size from the recesses of the other pairs,and the wire to be held being received in a pair of recesses of corresonding size and between said sleeve and tie bottom of the shank, andmeans for holding said sleeve in adjusted position upon said wire.

3. A binding post comprisingI a bifurcated shank, an elongated groovedead integral therewith and provided with notches in its edges adjacentto said shank, a sleeve on said shank having a plurality of pairs ofoppositely disposed recesses in its edge, each pair of recessesdifiering in size from the recesses of the other pairs, and the wire tobe held being received in seid recesses end between said sleeve and thebottom of said shank, and means for holding said sleeve in adjustedposition upon said wire.

II'1 testimony whereof I have aflixed my signature in presence of twowitnesses.
